IMPROVEMENT IN HYDRAULIC AND WIRE-ROPE PUMPING SYSTEMS.

Specification forming part of Letters Patent No. 208,704, dated October9, 1 78; application filed May 21, 1879.

To all whom it may concern:

Be it known that I, WILLIAM P. BARCLAY, of Virginia Oity, in the countyof Storey and State of Nevada, have invented a new and 1mprovedHydraulic and ire-Rope Pumping 7 System, of which the following is aspecification Figure 1 is a side elevation of my improved pumpingapparatus. Fig. 2 is a front elevation. Fig. 3 is an enlarged horizontalsection taken on line 00 m in Fig. 1.]

Similar letters of reference indicate correspondingparts.

The object of my invention is to provide apparatus for economicallyraising water from mines and deep shafts; and it consists in acombination of force-pumps and compound pump-rods, as hereinafterdescribed.

In pumping machinery such as is commonly employed in freeing mines fromwater, heavy rods of wood, joined and bolted together by iron plates,are used. These rods, to have the requisite strength, become excessivelyheavy, requiring counterbalancin g, thus throwing into the pumpin gapparatus a quantity of heavy material that requires to be oscillated ateach stroke of the pumps, thereby consuming an excessive amount of powerand rendering the action of the pump slow.

By my improvements these difficulties are overcome and the pumping iseffected economically. I employ as many force-pumps in the mine or shaftas may be required, placing them one above the other at suitabledistances apart. The pumps are provided with the usual inlet anddischarge valves placed one above the other.

Referring to the drawing, A is a pump-barrel, having the solid plunger Band valvechest 0, which contains the usual supply and dischargevalves,placed one above the other. The plunger B passes throughastufling-boxin the upper end of the pump-barrel and barrel D, that isplaced axially in line with the pumpbarrel, the latter being supportedby brackets attached to the delivery-pipe E, that is bolted to the topof valve-chest (J.

The delivery-pipe E extends up ward, and is provided with adischarge-spout, I and the valve-chest O is provided with asuction-pipe, G, which takes water from the bottom of the mine, or fromatank, H, which receives it from the next pump below.

The working barrel D is provided with a pressure-pipe,I, that extendsupward, and with a pipe, J, that extends downward, and is connected withthe top of the next working-barrel below.

At the mouth of the shaft or mine in which the pumping system isemployed there is a steam-cylinder, K, whose piston-rod L is connectedwith the working-beam M, which is provided with any of the well-knowndevices for producing parallel motion. The longer end of the beam ispivoted at a, and the shorter end thereof projects over the axial lineof the pressure-pipe I, and is connected by links I), one at each side,with wire ropes N, which extend downward, one upon each side of thedelivery-pipe E. O are cross-heads, each of which is provided withclamps c, that securely bind with the wire ropes. To one side of thesteam-cylinder K is attached a hydraulic cylinder, P, which is connectedwith the upper end of the pressure-pipe I, and is provided with a branchpipe, 0, which is connected with a force-pump.

The plunger f, which is fitted to the cylinder P, and works through astuffing-box in upper end thereof, is connected with the end of the beamM by links 3 The piston-rod of the steam-cylinder K extends through astuffing-box in the lower head of the cylinder, and is provided with aweightbox, It, in which weights are placed to increase the pressure onthe plungerf, and thus increase the pressure in the pipe I.

The operation of the pump is as follows: Steam bein g admitted to thecylinder K, so as to act upon the under surface of the piston, the beamM is forced upward. The upward movement of the plunger B draws the waterfrom the bottom of the mine or shaft, also from the tanks H. When thesteam-piston descends the pressure created by the downward movement ofthe plunger f forces water up the delivery-pipe E. The lowest pump inthe series delivers water to the lower tank, H, and the next above drawsthe water from the tank 11 and delivers it to another tank above, and soon to the upper pump in the series, which delivers the water to a sluiceor conduit, that conveys it away from the mouth of the shaft or mine.

It will be observed that the wire ropes may always be kept under more orless tension by the pressure of the water in the pipe.

Having thus described my inventioml claim as new and desire to secure byLetters lntent- 1. The combination of the stealn-cvlimler K, beam M, andhydraulic cylinder I, having the plunger f, pressure-pipe l, andauxiliary eylinder 1), for operating the water-forcing plung'ers, asherein shown and described.

2. The combination of the wire ropes N.

cross-heads, and plungersf B, as and for the purpose set forth.

2). A series of auxiliary working-barrels and pressure-pipe connectingthe same, for operating a series of mine pumps, as herein shown anddescribed.

4. The combination of the steam-cylinder K, rod L, lever M, plunger f,pressure-pipe I, and cylinder l,as and for the purpose specitied.
